According to Energy.gov’s Fact of the Week,
Transportation-related Employment was 16% Higher in 2017 Than in 1990
Very cool to know!
Since 1990 transportation-related employment as a whole grew by 16%, but employment within individual categories shifted. Manufacturing employment declined from 1990 to 2017 (except motor vehicle bodies and trailers), likely due to increasing automation. Other categories more than made up for that decline, such as truck transportation, transit, motor vehicles & parts sales, vehicle repair, construction, sightseeing, couriers, and transportation support. Total employment grew by 34% in the same time period.
